They are PRV's for each circuit:Don't have any idea what these fittings are,
I have my system pressure at the upper end of spec, about 2900. Even if these prvs were activating, I'd assume they would not release hydraulic fluid correct? They appeared to be seeping from where the prv threads into the valve block housing. Either way good call, I will throw the Guage on tomorrow to make sure nothing has gone out of whack.You might want to check your hydraulic pressure. If for some reason the main PRV is malfunctioning these BH PRV's may be unloading excessive main hydraulic pressure.
